All notable changes to this project will be documented in this file.
The format is based on Keep a Changelog and this project adheres to Semantic Versioning.
- Remove dead end method for network will move dead end to the trash and not remove observations
- Rewrite particle candidate to be easily parallelize
- Check strictly increasing coordinates for RegularGridDataset.
- Grid mask is check to replace mask monovalue by 2D mask with fixed value
- Add method to colorize contour with a field
- Add option to force align on to return all step for reference dataset
- Add method and property to network to easily select segment and network
- Add method to found same track/segment/network in dataset
- Now time allows second precision (instead of daily precision) in storage on uint32 from 01/01/1950 to 01/01/2086 New identifications are produced with this type, old files could still be loaded. If you use old identifications for tracking use the --unraw option to unpack old times and store data with the new format.
- Now amplitude is stored with .1 mm of precision (instead of 1 mm), same advice as for time.
- Expose more parameters to users for bash tools build_network & divide_network
- Add warning when loading a file created from a previous version of py-eddy-tracker.
- Fix bug in convolution(filter), lowest rows was replace by zeros in convolution computation. Important impact for tiny kernel
- Fix method of sampling before contour fitting
- Fix bug when loading dataset in zarr format, not all variables were correctly loaded
- Fix bug when zarr dataset has same size for number of observations and contour size
- Fix bug when tracking, previous_virtual_obs was not always loaded
- Allow to replace mask by isnan method to manage nan data instead of masked data
- Add drifter colocation example
- GridCollection get_next_time_step & get_previous_time_step needed more files to work in the dataset list. The loop needed explicitly self.dataset[i+-1] even when i==0, therefore indice went out of range
- TrackEddiesObservations.filled_by_interpolation method stop to normalize longitude, to continue to have same beahviour you must call before TrackEddiesObservations.normalize_longitude
- Use safe_load for yaml load
- repr of EddiesObservation when the collection is empty (time attribute empty array)
- display_timeline and event_timeline can now use colors according to 'y' values.
- event_timeline now plot all merging event in one plot, instead of one plot per merging. Same for splitting. (avoid bad legend)
- Identification file could be load in memory before to be read with netcdf library to get speed up in case of slow disk
- Add a filter option in EddyId to be able to remove fine scale (like noise) with same filter order than high scale filter
- Add EddyQuickCompare to have few figures about several datasets in comparison based on match function
- Color and text field for contour in EddyAnim could be choose
- Save EddyAnim in mp4
- Add method to get eddy contour which enclosed obs defined with (x,y) coordinates
- Add EddyNetworkSubSetter to subset network which need special tool and operation after subset
- Network:
- Add method to find relatives segments
- Add method to get cloase network in an other atlas
- Management of time cube data for advection
- Add an implementation of visvalingam algorithm to simplify polygons with low modification
- Add method to found close tracks in an other atlas
- Allow to give a x reference when we display grid to be able to change xlim
- Add option to EddyId to select data index like --indexs time=5 depth=2
- Add a method to merge several indexs type for eddy obs
- Get dataset variable like attribute, and lifetime/age are available for all observations
- Add EddyInfos application to get general information about eddies dataset
- Add method to inspect contour rejection (which are not in eddies)
- Grid interp could be "nearest" or "bilinear"
Now to have object informations in plot label used python
`format`style, several key are available :- "t0"
- "t1"
- "nb_obs"
- "nb_tracks" (only for tracked eddies)
